Joe Dirt (David Spade) is a custodian who had a poor upbringing, after he was left behind by his parents at the Grand Canyon and left to fend for himself. As a baby, he had a mullet wig implanted because the top of his skull never formed.

In Futurama, Scruff (voiced by David Herman) works as a janitor for Planet Express, if you can call it work. He’s generally apathetic about his job and spends most of his time in the pages of porn magazines.
